Congenital chylous ascites: the roles of fibrin glue and CD31.

UNLABELLED: A 6-month-old male infant who presented with abdominal distension and congenital chylous ascites was diagnosed. He was initially refractory to conservative therapy, and then was completely cured with ligation of megalymphatics and fibrin glue application. Immunoperoxidase staining for CD31 on the biopsied peritoneal tissues highlighted the lining cells of lymphatic spaces, which indicated lymphangiectasia. CONCLUSION: This case emphasizes the effectiveness of lymphatic ligation of the retroperitoneal megalymphatics in conjunction with fibrin glue application to cure congenital lymphangiectasia.

Clinical use of erythromycin in children with gastrointestinal dysmotility.

Intolerant feeding is a common symptom in gastrointestinal disorders which is commonly found in systemic diseases. Prokinetic drugs play a role in management. A low dose of erythromycin has an effect on improvement of antroduodenal motility and gastric emptying in children and adults. The objective of this study was to evaluate the efficacy of intravenous erythromycin in the treatment of GI dysmotility in children. Retrospective studies were performed in the Department of Pediatrics, Siriraj Hospital, Mahidol University between 1996 and 2000 in 22 patients with intolerance of feeding due to GI dysmotility. Their ages ranged from 11 days to 12 years (42.1 +/- 48.1 months). The patients were divided into 2 groups: 12 critically ill and 10 non-critically ill patients. Dosages of intravenous erythromycin were 1-3 mg/kg/dose every 6 hours. The result of treatment was evaluated as: good (tolerant feeding), fair (tolerant feeding but needing erythromycin for longer than 1 month) and failed (intolerant feeding). All non-critically ill patients had improved symptoms with 9 +/- 4.3 days duration of treatment. In the other group, 8 patients had good results with 10.9 +/- 6 days of treatment. Two patients needed the drug for longer than 1 month and the other 2 patients did not respond and died due to severe infection. Low dose intravenous erythromycin had good efficacy in the treatment of intolerant feeding related to GI dysmotility in children.

A randomized clinical trial comparing the efficacy of ranitidine and famotidine on intragastric acidity in critically ill pediatric patients.

We examined the efficacy of intravenous ranitidine and famotidine on raising intragastric pH in each of 10 critically ill pediatric patients. The severity of illness was assessed by using the modified zinner index score. The study had 3 phases and each phase took 24 hours. Intragastric pH was measured by continuous pH monitoring digitrapper for 72 hours. In phase 1 and 3, the patients did not receive any H2 blockers. In phase 2, they were randomized to receive intravenous ranitidine or famotidine. The majority of cases had intragastric pH < 4 in day 1 (base line). Ranitidine and famotidine increased total time of intragastric pH > or = 4 from the base line during day 2, 38.2 +/- 16.9 per cent and 60.3 +/- 24.8 per cent respectively (P0.004), but there was no statistical difference between the 2 medications in both Zinner index score 1 and score greater than 1 group (P 0.08, 0.45). Three cases in the famotidine group had successful prophylaxis with total time pH > or = 4 more than 80 per cent. Famotidine appeared to have a trend toward increasing intragastric pH in critically ill pediatric patients.

Itraconazole for treatment of oral candidosis in pediatric cancer patients.

Oral candidosis commonly occurs in malignancy children undergoing antineoplastic chemotherapy. Inadequate response to antifungal treatment leads to a risk of disseminated infection. The aim of this study is to evaluate the efficacy and side effects of itraconazole on treatment of oral candidosis. Fourteen children with malignancy undergoing chemotherapy received itraconazole 100-200 mg/day for 10 days to treat oral candidosis. The severity of disease was defined as mild and moderate depending on the number of lesions and symptoms. Oropharyngeal lesions and symptoms were recorded initially and daily. Blood chemistries were done on day 0, day 10 and day 16. The overall response rate was 87.5 per cent. The mild group (4 cases) had a response rate of 100 per cent which had lesions and symptoms resolved on day 2 and day 1.5 +/- 0.7 respectively. The moderate group (10 cases) had 8 responders (80%) whose lesions and symptoms resolved on day 6 +/- 2.5 and day 4.1 +/- 2.3 respectively. Side effects and abnormal blood chemistry values. were not seen.

Upper gastrointestinal endoscopy in children with recurrent abdominal pain.

Over a 3 year period from 1992 to 1995, 62 patients with recurrent abdominal pain (RAP) underwent upper gastrointestinal endoscopy showing normal findings in 30 patients (48.4%), gastroduodentis 17 (27.4%), H. pylori gastritis 11 (17.7%) and esophagitis 4 (6.5%). Duodenal or gastric ulcer was not found. This study demonstrated more evidence of increased prevalence of organic causes of RAP than previous reports. Duration of illness of more than one year and vomiting were more common in H. pylori gastritis. Other symptoms including diarrhea, constipation, nocturnal awakening and pain related to meals could not differentiate between organic and functional cause. Major cases of H. pylori gastritis and gastroduodenitis responded to triple drug therapy and H2 blockers respectively.

Helicobacter pylori infection in Thai children with recurrent abdominal pain.

Sixty-five children with recurrent abdominal pain underwent gastrointestional endoscopy which showed Hp gastritis without duodenal ulcer in 16.9 per cent of cases. The prevalences of infection in recurrent abdominal pain and asymptomatic children were not different. Either urease test or histological method was appropriate for diagnosis of this infection. Triple therapy including bismuth subcitrate, amoxicillin and metronidazole improved abdominal pain symptom in 72.7 per cent without any side effect.

Gastric emptying pattern in Thai infants.

Gastric emptying of milk from the stomach of Thai infants shows a biphasic pattern. At 40 minutes the amount of stomach contents is more than at 20 minutes. At 100 minutes, only 16 per cent of the initial amount was recovered. The results of our study can be used as a standard reference for further study in infants with other diseases.
